.SH DESCRIPTION
|
|
\fBarecord\fP is a command-line soundfile recorder for the ALSA soundcard
|
|
driver. It supports several file formats and multiple soundcards with
|
|
multiple devices.
|
|
|
|
\fBaplay\fP is much the same, only it plays instead of recording. For
|
|
supported soundfile formats, the sampling rate, bit depth, and so
|
|
forth can be automatically determined from the soundfile header.
